INTRODUCTION
Education is a conscious and planned action to create a learning atmosphere and learning process so that students are able to develop their potential and skills (Sanjaya, 2008: 2). One of the efforts is by implementing a curriculum that supports the education. According to Machali (2014: 72) curriculum is capable in directing the learners to adapt to their environment, both physical and social environments that are constantly changing.
The development of curriculum 2013 is currently prioritizing learning by educators and direct experiences and processes of learners. The implementation of curriculum 2013 is expected to encourage students to think more creative, innovative, fast, and responsive and prioritize the principle of religion in life, being a person who has contributions to the development of society and Nation.
Part of the components in the curriculum such as learning tools, effective learning process and supportive learning media are important in implementing the curriculum because it relates to the learning system that packed in curriculum. According to Mahnun (2012: 33) Media is part of the learning components. Benefits and function of media in the learning are perceived by both educators and learners. According to Latifah (2016: 44) Learning resources and learning media that help learners and educators are student worksheets. The purpose of students ' worksheets is to improve student performance.
One of the causes of student low achievement is that educators still apply the most popular learning method. According to Lutfiah (2014) one of the causes of low achievement because the learning process is still dominated by educators and does not give learners the opportunity to develop their abilities. Physics is still considered difficult by the learners especially the material taught is abstract. Educators are expected to choose a model or learning method that matches the learning process. According to Sinabariba (2017) learning model can be interpreted as a systematic procedure in organizing the learning experience to achieve the learning objectives.
One of the proper models is ICARE learning model that can be implemented in curriculum 2013. According to the Ministry of National Education "The use of ICARE model greatly gives learners opportunities to apply what they have learned". Similarly, Wahyudin (2010: 31) also states that ICARE is a learning model that organizes learning activities in a more contextual oriented life skills, and learning approach focus on: active, creative, and joyful learning.
The results of research conducted by Dwijayani et al. (2017) concluded that: ICARE learning Media met the criteria for validity, practicality, and effectiveness. Development research was also conducted by Mustofa (2017: 67), stating that "products developed are appealing for learning in a classifying and independently class and then the result of expert validation and testing of ICARE learning models on Class expansion is feasible ".

Problem of Research
The researcher has conducted discussions with one of physics teachers in the targeted school as a pre-research observation. Based on the discussion, the researcher obtain the information that educators are still putting popular learning tool. Learning plans and student worksheets are made only to support school administration. Educators are expected to develop teaching materials and media to suit the demands of the curriculum by considering the needs of learners. Good selection of media is also needed in the learning process that gives learners the opportunity to be actively involved.
The use of learning media that supports for experimental activities, laboratory for instances, has not been adequate as a learning resource. According to (Trianto, 2009: 223), "The knowledge and understanding of learners is empowered through the provision of media learning in every experimental activity so that learning situation becomes more meaningful, and impressive".

Research Focus
Based on the advantages that the ICARE learning model has, the researcher plan to develop an alternative media supporting the ICARE model called students' worksheets to provide the opportunities for learners in applying the concepts obtained. According to Suyitno (Fannie, 2014:98) student worksheets are one of the alternative learning for learners because student worksheets help them to add information about concepts learned through activities Study systematically.

General Background of Research
This research was conducted in MAS Darul Ihsan Aceh Besar which located in Tgk Glee Road, District of Siem, Darussalam, Aceh Besar. This study conducted in the second semester of 2018/2019 academic year. The research time was from April 27 to July 20, 2019. While the assessment conducted by the LKPD validation team held from 28 April to 17 May 2019 in UP-PPL and Micro Teaching room of Syiah Kuala University.

Sample of Research

According to Arikunto (2010:117) "samples are part of the population (partial or populationresearched representatives). The subject in this study was 28 students of the X-IPA 4E class in the MAS Darul Ihsan 2018/2019. While the object in this research was ICARE learning model.

Instrument and Procedures
In this research, There were two types of instruments collected, namely the validated students' worksheets and students' response sheet. Validated students' worksheets whicht support the ICARE learning model was validated by two validators i.e. lecturers of physics and Mathematics education, Faculty of Education to Assess the feasibility of students worksheets. The validation sheet in this study was a written statement. Each validator provided an assessment of the students worksheets that have been developed by giving a score of five (very good) or a score of four (Good) or a score of three (Enough) or a score of two (Poor) or a score of one (very poor). After the assessment conducted by the validators, the validation sheets was handed out to the researcher tobe analyzed descriptively qualitative.
The student response sheets in this study was 10 written questions. Alternate choice of the answer is a score of five (very good) or a score of four (good) or a score of three (enough) or a score of two (poor) or a score of one (very poor) and provide a reason on each answer. This response sheets were given to learners after teaching and learning activities using students worksheets to support ICARE learning model that has been developed, then learners provide assessments and Responses to the students' worksheets. Once the assessment hadconducted, student's response sheets were handed out to the researcher to be analyzed descriptively quantitative.

Data Analysis
